Sprint and At&t Are My First Choices...
Sprint: 250.00 Deposit Refundable After 1 Year.
At&t: Go Phone Pick Your Plan, Since at&t's deposit is $750.
And Finally T-mobile, I would do the no contract flex-pay. No deposit, but around 300.00 for the blackberry pearl I want....
Still trying to choose.... It's really hard because I don't want to get the "wrong" carrier, and then realize I hate them, then try and get my money back again, and wait and try another... It's not worth the hassle to me.
Have you checked Sprint's great plans for SERO on www.sprint.com/sero?
I'm pretty sure Sprint would be your deciding factor.
Even with a SERO Blackberry data plan, that is unmilited (no cap like other carriers), EvDO speeds, and allowed to tether (phone as a modem).
If you don't mind me asking, why did you make the choices (carriers)?
I'm trying to help you make your best choice, even thogh I work for Sprint, I'm not biased...not too mush...lol).
I honestly try to help EVERYONE who asks for my assistance.
