so the cons with tmobile and cingular:
1. not worth it cuz of the high price. even though u can do a hack so u dont have to pay for tether. i wont tell u cuz it is against the rules in this forum.
2. not worth it cuz how slow speed (almost like browsing with 56k modem back in the 90's)
For T-mobile, you have to pay $19.99 for the Blackberry data plan that includes tethering. (There are other plans available for Blackberry like a plan that combines voice, data, and text messaging.)
For AT&T, you have to pay $29.99 and if you want tethering, it's another $69.99 extra per month.
With Edge speed, it's in between dial up and DSL speed. Expect to get around 115 kbps.
If speed concerns you, than yes, I do recommend getting Verizon or Sprint. But if I have the money, I think I will go to Verizon instead.
