Quick Question - Unlocking

Hi I'm considering purchasing the Nexus One and selling my HTC HD2 T-Mo edition for one. I would like to know, can I unlock a T-Mobile version to work with AT&T 3G?
I'm hoping to be able to use 3G on both carriers, is this possible?
No, not possible.

The Nexus One is unlocked by default but because of hardware limits you can't use 3g on AT&T with a t-mo version and viseversa.

search is your friend. and this is also as obvious as balls

HTC One Dev Edition radios?

Hi all, is there any difference between the radios on the Dev edition vs. the normal one? For instance, if I have the Dev edition, what's stopping me from flashing an AT&T, T-Mobile, or Sprint ROM? Shouldn't they all be compatible with my device? Does flashing any of those affect my radios?

The Developer Edition radio is set up for GSM service by default. I know there's a setting to change it to CDMA, but I have yet to see somebody post on trying it with their Sprint or Verizon HTC One. If you're on AT&T or T-Mobile, it works. If on Sprint or Verizon (or other CDMA provider), maybe. I would be curious since my friend has a One with Verizon. It pains me to see all that bloatware on his phone that can't be removed or disabled.
Short answer to your question. Nothing is stopping you from flashing an AT&T, T-Mobile, or Sprint ROM. But I fail to see why somebody would want to do that if they have the Dev Edition. Unless they really like bloatware and carrier restrictions.

Physical difference?

Is there a physical difference between Sprint HTC Ones and ATT HTC ones?
What I am trying to ask is do they have a physical factory preset as to which phone accepts the different frequency technologies or is it all just software and firmware that affects the phone?
Sorry if this is a dumb question I just have never been clear on that subject.:silly:

There are several hardware differences between the devices including but not limited to radios.

Best variant

I am looking at getting a M7 as a media player. I like the unlocked bootloader over the old S4 that I will end up selling. I dont go crazy with custom ROMs but id like a good fast ROM, maybe CM.
Question is, which is the best variant of the device for custom roms. specifically the sprint variant seems to be the cheapest because the lock out ESN often. is there any limitations to the sprint variations that mean i need to spend more?

You need to take a look at each variant to see which works best for you. Sprint & Verizon variants are CDMA and the rest are GSM. GSM phones are far more prevalent internationally than CDMA and are or can be easier to customize thus more options. Your call!

Im refering to mod-ability. I will not be using this as a phone so I dont care about the radio. Like for the G3, verizon has a locked bootloader but t-mobile is unlocked.
Is there an issue flashing CMDA roms to the sprint variant if phone is not needed?

You should only flash ROMs that are compatible with your variant. The CDMA phones have different partition tables than their GSM variants. This could cause the phone not to operate. So, if you have a Sprint phone then only put ROMs that are compatible with the Sprint variant. There is a separate forum for the Sprint & Verizon variants.

And you said there is more variety for the GSM versions. I can find sprint phones for $80, is there anything that justifies an extra $40 for a GSM variant?

I'm not a marketing guru but Sprint has limited coverage as a phone and limited support from custom tweakers, while the GSM phones are plentiful and can be used in more locations. Bottom line, if the it meets your needs then get the Sprint variant but should you need it as a phone down the line remember you have very limited options.

World Phone?

Hey this may seem very noobish of a question but i just wanted to make sure...
Someone recently offer me a deal for the A71 5G (sprint), and I wanted to know if it had a sim slot to convert it to GSM, or is it strictly only CDMA?... Now I am aware devices from Verizon can do both and that iPhones from Sprint can use GSM sims, so I curious if it still applies about this device, or do I have to attempt to unlock it from its carrier? Thanks!
