Verizon, not too long ago, announced that they would be opening their networks to other devices and applications some time next year as soon as they came up with some standards those two items had to meet. AT&T, they are opening their network now, as in right now.

In fact, AT&T’s wireless network has been open to other devices and applications from day one; it just wasn’t advertised before now. So you can take you custom made hacked-to-hell-and-back breadboard made smart phone in there, and they will either activate it, or give you an activated SIM card for it.
And, you don’t have to have a contract either, no contracts necessary, which is convenient since you never know how long that Franken-phone of yours will last. So technically, AT&T is the most open network in the biz right now, and they are also the only major network not part of the OHA, so take that Google! If you decide to whip together your own mobile device, I am pretty sure it has to use a GSM radio, as that’s what AT&T’s network is made up of, but chances are you’d be satisfied just being able to activate any GSM device you want on their network, so you could go buy a phone from Alltel or T-Mobile and then have it activated on AT&T’s network if you wanted.

Alltel is a CDMA carrier. They purchased smaller carriers that used GSM phones and haven’t forced those users to switch to CDMA compatible phones. But, they won’t activate new accounts with GSM as far as I’m aware.
who gives a crap about the att and their 2.5g edge network, yes that’s right not a 3g network. go with the real 3g network verizon.
Thats right. Go ahead and jump on a network that uses proprietary technology. Cause we all know how well proprietary technology works out for the end customer. No choice of phones but what Verizon says you can use, and then just for kicks, they tell you what functionality your phone will and will not work on their network.
I’m not so sure about the 2.5G comment on AT&T either. My 3G signal on my nokia N95 comes on when I’m locked in. My download speeds are amazing.
