Cricket Wireless stores


Recommended Posts

Hello,

 

Usually a phone that is bought from a carrier like Cricket Wireless, or their parent company AT&T, Verizon, Sprint, etc. has apps from the carrier pre-installed on it.  There might also be some default settings which are different, like having the carrier's home page for the web browser and so forth.  Sometimes a device may have a different amount of memory or storage, too, but that goes for models that are sold online, too.

 

Regards,

True indeed, Aryeh - something which I rediscovered with the current trend toward SoCs (which started years ago - and with Qualcomm).   One of the earliest Android phones was the original Galaxy Nexus, which shipped in multiple varieties - with each one aimed at a specific carrrier's network.  I myself had the toro version, which was aimed at Verizon's network.  As a result, I could NOT use a ROM developed for non-toro Nexus phones - with one exception - I COULD use ROMs that were developed around the "tuna" spec - "tuna" was a generic specification that worked on all Galaxy Nexus phones, not just one.  Still, tuna could not take advantage of specific features unique to each specification..  Not fun for developers, and not fun for phone OEMs, either.  Therefore, what if the ONLY differences were in the firmware - not the hardware?  Enter the generic SoC - and, naturally, one of the earliest such came from Qualcomm.  Even today, Qualcomm is the largest supplier of generic SoCs in the Android - and non-Android, incidentally - marketplaces - though they are far from the only one.  My S7 is driven by the Qualcomm Snapdragon chipset - a generic SoC.  It is hardly unique - even the S7 has an alternative SoC option itself - from Samsung - the Exnyos SoC.  Since the S7, the two SoC brands have done battle - Qualcomm in North America, and Exnyos everywhere else.  (While you can GET Exnyos-driven Samsung phones in the United States - Amazon in partcular is the largest source of them - they are NOT covered by US warranties.)

 

As I pointed out above, my S7 is driven by the Qualcomm Snapdragon generic SoC.  My S7 has another feature - Verizon branding - literally - all over the phone - including the original firmware.  If the phone was blown off the original contract, the IMEI gets blacklisted - it's called being "network locked", and you can't take it back to that carrier.  So I'm screwed, right?  Surprisingly, no - what I need is a SIM from another carrier - even an MVNO works, as long as I use a SIM from a network OTHER than the one that locked out the IMEI.  I had my Galaxy Nexus at the time, and I had service with the Safelink Wireless division of Tracfone, the largest MVNO in all of North America - and I did NOT want to leave.  Fortunately, I didn't have to - Tracfone - and thus Safelink - uses TWO carrier networks; Verizon being one (and where I was at the time) and T-Mobile being the other.  What I needed was a SIM for T-Mobile's network to match my new phone - which was an order away.  Porting the phone number itself - from Verizon's half of the Safelink/Tracfone network to the T-Mobile half - was doable online and cost exactly squat.  Service since then has been problem-free, along with gaining several benefits due to the carrier switch (such as Voice over Wi-Fi).

I can now purchase a new (unlocked OR T-Mobile-branded) phone; migration itself will be a yawn (the reason I can buy a T-Mobile phone is because I am using T-Mo's network, despite being on an MVNO) - the one reason it is unlikely that I would is because I am with an MVNO, and thus it would be easier for ME to handle my own migration, as opposed to having to worry about it being fumbled by the sales folks - which DOES happen all too often.

    • Researchers claim Microsoft's quantum breakthrough is flawed by basic Python errors by Karthik Mudaliar Microsoft's aggressive roadmap to deliver a commercial quantum supercomputer by 2029 has now hit a bit of a snag, and it's not because of a complex sub-zero dilution refrigerator, but rather because of a few lines of basic Python code. A new critique published in the scientific journal Nature argues that simple software errors effectively manufactured the breakthrough that Microsoft's foundational research claimed back in 2025 into Majorana-based topological qubits. Topological quantum computing, the path that Microsoft chose for its research, relies on creating and controlling "Majorana zero modes." These are exotic quasiparticles that theoretically offer vastly superior error resistance compared to the highly sensitive superconducting qubits currently being championed by rivals like Google and IBM. However, physically proving you have created these particles requires sifting through massive amounts of complex electrical conductance data to isolate a specific "topological gap." Because of the sheer volume of data, physicists rely heavily on custom software pipelines to process the results. This is where the Python scripts come in. Now, according to the critique, Microsoft’s data processing software contained fundamental programming errors that ultimately skewed the published results. By mishandling data arrays or deploying incorrect logic within the Python script, the software supposedly discarded "noisy" or contradictory data. Which is why it only highlighted the specific electrical measurements that supported the topological-gap claim. The researchers behind the critique argued that this makes the findings invalid, suggesting the heralded "quantum leap" was actually a false positive generated by bad code and not a product of groundbreaking physics. However, Microsoft is pushing back hard against these allegations. The Redmond giant has formally rejected the criticism, saying that it's just a minor anomaly rather than a fatal flaw. According to the company, while there may have been a minor oversight in the data parsing scripts, it does not alter the fundamental reality of their physical experiment. Just weeks ago, Microsoft unveiled the Majorana 2 quantum processor, a milestone so significant that the company boldly accelerated its timeline for a commercial quantum supercomputer from 2035 down to 2029. But the new software allegations reopen an old wound. Microsoft's quantum division faced a remarkably similar crisis when a landmark 2018 paper on Majorana particles was famously retracted in 2021 after independent physicists discovered the data had been inappropriately cropped. That historical baggage makes the current Python-related allegations particularly sensitive. If the foundational math and data processing for the 2025 breakthrough are genuinely flawed, the highly anticipated 2029 commercial timeline could easily be delayed or, worse, cancelled.
