This is a great phone, if your primary use is email; If you really need voice service, and only occasional email, consider the Audiovox SMT5600 instead. Regardless, I hope you have more luck with Cingular than I did. There's simply not enough time or room to recout my problems with Cingular but I'll provide a brief recap.I have service with Cingular and with AT&T.; The problems began when I tried to merge my two services into one account (Cingular did acquire AT&T;, right?), upgrade my service plan, and upgrade the AT&T; phone. Simple enough, right? Wrong.After (literally) four visits to the store, 10+ phone calls (and speaking with over 30+ people), and completing several forms on the web I thought I had finally solved the problem and everything was fine. THEN my phone showed up ... it was the wrong one. Attempts to get the problems resolved on the phone failed (we can't do that here), attempts to return it to the store failed (that was sent to you by our phone sales group, you can't return it here), and a final desperate attempt to resolve it through Cingular's Office of the CEO was meet by "you shouldn't have tried to transfer your service from AT&T; to Cingular" (i.e. it's your fault) and "you're trying to order the most expensive phone we have, what do you expect us to do, give you a free one?" (i.e. you're trying to cheat us).My experiences can basically be catagorized in the following fashion:* You're an AT&T; customer, you'll need to call Cingular for that.* You're a Cingular customer, you'll need to call AT&T; for that.* You're a corporate customer, we're the retail group. You'll need to call business services for that.* You did that over the phone, you'll need to take up that problem with telesales.* You did that in the store, you'll need to take up that problem with them.* That can't be done over the web.* I don't know how to do that.I think the crowning touch however, was the retail store that refused to sell me the phone because my account is tagged as a "sponsored" account that gets an equipment discount. The manager wanted to sell it to someone who would pay full price!Good luck!...msg
