Regarding switching Sprint to Straight Talk, which I just did... There is truth and wisdom in concerns about data use if you're used to Sprint. A) ST 3G is way the heck faster but B) It's unofficially restricted, esp. on AT&T SIM cards. Long story short, don't switch to ST if you're going to abuse data. They won't like you and you may lose your number.
Consensus is if you're very careful to provide all the correct information (Sprint acct # and PIN which you can get from their site, and correct address/zip), it should go smoothly by swapping through the ST site.

But they got me squared away and my Pre 3 was working before I hung up the phone.
Yes, Verizon's CDMA. Straight Talk now uses all of the big 4, but the Straight Talk BYOP program is for GSM phones. Their CDMA selection is restricted. (God I'm glad to be off CDMA!)

But yes, you won't get fauxG on T-Mo if they haven't switched towers as you said. Check a crowd-sourced T-Mo coverage map here: Sightings of T-Mobile 3G/4G/HSPA+ coverage on 1900MHz (PCS/UMTS band II)
If you get your own SIM, right now you can't get the AT&T SIM through the ST site for some reason, only the T-Mo. Think the regular sized AT&T SIM is still available at walmart.com, though. That's where I got mine. The package with one-month service saves ya $5 too.
