I took the second quiz yesterday. Wasn't 100% satisfied with the results (AT&T) but they gave me some ideas. SERIOUSLY me and you are in the almost EXACT same boat! I just have to have more of a smart phone for keeping in touch with family and college online.

I am using the Motorola Karma QA1 and it went kaputz on me yesterday. My screen is not showing up and I have no idea why. I have been through nokias, pantechs, samsungs, sony's, and even one very unique phone for international travel... I am thinking I need to stop buying the cheaper phones and just invest in a good phone since really I use it for everything. I hope you get good answers because I'm looking for a new one too. My husband has the Samsung Impression (I think?) and I'm considering just getting the same phone or something Samsung again.
