I will download when a jailbreak is released for my iPod Touch 2G. I just hope they fixed the Wi-Fi issues and the battery draining problem.

What Wi-FI issues were these? My 3gs would intermittently fail to auto join my network and would refuse to rejoin when I try manually.

I've upgraded my iPod Touch 2g to iOS 4.1.

I was surprised to see the Game Center return - wasn't it to be for iPod 3g and up only?

Other than that it's working smoothly. Significantly snappier? than iOS 4.0.x.

For unknown reasons it's on the iPod Touch 2G but not the iPhone 3G, no idea why tho.

I have a Wireless-N Linksys router and when I barely move away from it to, lets say the living room or kitchen, it disconnects because it can't find a signal. With iOS 3.1.2 I didn't have any of these problems.

Well, looks like my friend has the same problem as I do on his iPod Touch 3rd gen. The battery dies so quickly with iOS4 and it gets about twice as worse with iOS4.1

So it's worse now?! I can't downgrade to 3.1.2 because my SHSH hash's were not saved, so I am stuck? :(

Likely won't be a jailbreak for this as it will just get fixed in 4.2. So i'd wait for 4.2 ... I'm getting an iPod Touch 4G for Christmas and it will likely come with 4.2 if not 4.1 so I really hope a jailbreak for 4.2 should come around December/Early 2011. And this will hopefully bring an iOS 4 jailbreak to the iPad too. I'd laugh if they manage to hack the iPod Nano in some way to play videos :L

I've been having the exact same problem. If the phone is turned on whilst at home, it connects to wi-fi with no problem. If I leave and come back, however, it doesn't join the network automatically, and if I manually try to join it asks for the password. When this is (correctly) entered it insists that the password is wrong.

I've also been having problems with receiving calls and changing the sound output (headphones, speaker dock etc.), both of which sporadically cause the phone to slow to a crawl. Hopefully the new firmware addresses both of these problems, although if my experience with an iPhone so far is anything to go by, we'll be disappointed.

how does ios 4.1 compare to ios3.X on the ipod touch 2g?

Well, I've just finished installing it, and I was right to be skeptical. Most apps instantly crash when I try to open them (including Safari and Mail). Superb. This thing has been nothing short of a **** take since the moment I got it. I just hope I can still get a refund.

Sounds like a dodgy update or you may have some faulty hardware - your problems are not common.

Definitely noticing a speed increase on the iPhone 3GS, much smoother. (Y)

Me too - I love my 3GS!

I noticed a nice speed increase on my iPhone 4, and it was already fast on iOS 4. :p

So far the only games that work with Game Center are Flight Control (.99) & Mrs. Pac-man (4.99)

Enigmo, Firemint Real Racing, and Zen Bound 2 are also updated for Game Center.

    • As I've been usually saying lately - we all can thank "AI" for this.
    • Friday Windows 11 preview builds are here. Insiders in the Experimental (formerly Dev) and Beta Channel can download builds 26300.8697 and 26220.8690. My Windows11 device on the Preview Channel just got 26220.8728. My guess is this build is a nightly update from 26220.8690.
    • Traffic has a surprisingly unexpected impact on your surroundings by Sayan Sen Image by Radik 2707 via Pexels A collaborative study by researchers from several Israeli institutions found that everyday pollution from traffic and industrial activity measurably changed the atmospheric electric field over the Tel Aviv metropolitan area, providing new evidence of how human activity can influence the lower atmosphere. The research was led by Dr. Roy Yaniv of the Hebrew University of Jerusalem and the Gertner Institute at Sheba Medical Center, Dr. Assaf Hochman of the Fredy & Nadine Herrmann Institute of Earth Sciences at the Hebrew University, and Prof. Yoav Yair of Reichman University. The study also involved Itay Froomer, a student from Hadera High School and the Israeli Museum of Medicine and Science (Technoda), who carried out the work as part of the Ministry of Education's 5-unit physics research track. The researchers focused on the atmospheric electric field under fair-weather conditions. Even in the absence of storms, a weak electric field naturally exists between Earth's surface and the atmosphere. One of the main ways scientists measure this field is through the Potential Gradient (PG), which is the inverse of the vertical component of the electric field. PG is a key part of the global electric circuit, a planet-wide system of electrical currents maintained by thunderstorms and electrified clouds around the world. Scientists have long known that the atmospheric electric field can be influenced by factors ranging from large-scale atmospheric processes to local weather conditions such as dust, fog and clouds. Human-made pollution is also known to play a role, but understanding exactly how urban emissions affect the electric field close to the ground has remained an area of ongoing research. To investigate this relationship, the team analyzed measurements from a newly installed electric field mill, an instrument used to continuously monitor the strength of the atmospheric electric field. The instrument was installed at the Center for Technological Education (Roter House) in Holon and became operational in August 2024. It was funded by Israel's Ministry of Education and the Holon municipality. The electric field mill forms part of a broader monitoring network that includes nearby meteorological stations and air-quality monitoring sites. This allowed researchers to compare electric field measurements with detailed weather data and pollution records to better understand what was driving changes in the Potential Gradient. The study focused on two major urban pollutants: fine particulate matter (PM2.5) and nitrogen oxides (NOx), both commonly produced by vehicle traffic and industrial activity. PM2.5 refers to microscopic airborne particles small enough to remain suspended in the atmosphere for extended periods, while NOx is a group of gases released during fuel combustion. Researchers examined daily, weekly and seasonal patterns in the atmospheric electric field and compared them with changes in pollutant concentrations. Their analysis revealed a clear relationship between NOx levels and changes in the Potential Gradient, particularly during morning and evening rush hours when traffic emissions were at their highest. “What we observe is a direct physical link between emission peaks and electrical variability,” explained Dr. Roy Yaniv. “NOx reduces atmospheric conductivity very quickly, so the electric field responds almost instantaneously during traffic rush hours.” Atmospheric conductivity describes how easily electrical charges move through the air. According to the researchers, nitrogen oxides rapidly alter this conductivity, causing a near-immediate response in the electric field. PM2.5, however, was associated with a delayed response. The researchers attributed this difference to the particles' longer atmospheric residence time, meaning they remain in the atmosphere for longer periods, as well as their different microphysical interactions with surrounding air and atmospheric components. The study also identified a pronounced "weekend effect." In Israel, traffic volumes and some industrial activity decline significantly on Fridays and Saturdays. During these periods, concentrations of both NOx and PM2.5 dropped, and corresponding changes were observed in the atmospheric electric field. “The weekend signal demonstrates just how sensitive the electric field is to changes in human activity,” the researchers noted. “When emissions decline, the electrical environment adjusts at once, providing a high-resolution indicator of urban atmospheric conditions.” The findings showed that pollution levels can influence not only the chemical composition of the atmosphere but also its electrical properties. Researchers said the results strengthened the case for using atmospheric electricity as an additional tool for environmental monitoring, particularly in densely populated urban areas where anthropogenic, or human-caused, influences are most pronounced. The study also pointed to potential public health applications. By combining air-quality measurements with observations of atmospheric electricity, researchers said they could gain a more complete picture of how urban atmospheric conditions change over time. “Integrating air-quality data with electric-field measurements gives us a clearer picture of how the lower atmosphere evolves moment by moment,” the researchers added. “It’s a framework that can support both scientific insight and practical environmental decision-making.” Beyond the scientific findings, the project highlighted a collaboration between universities, public institutions and secondary education. Researchers said the work demonstrated how students could take part in real-world environmental research while contributing to studies of air quality, atmospheric processes and their potential effects on society.

    • We aren't even at the all-star game and Microsoft is talking about an update that will most likely be released during the World Series if not after. A lot can happen in the world between now and the 2026 World Series, including the 2026 FIFA Cup. Tell me about it again after the FIFA Cup is concluded. That should allow plenty of time to prepare for it.
    • Great, tell me when I have a "Bad Pool Caller" elsewhere not in Windoze.
