This is what I was asking about in my other post. Since you have At&t, they have an exchange policy to either replace your phone or allow you to upgrade. All cellular providers use a third party company by the name of lock-line. With at&t, you can order insurance exchange or warranty exchange programs to your services, here's the difference.
In insurance, i think it's $5 extra to your bill a month, plus a $35 deductible per claim. Depending on what phone you have, you can call and order a new phone. Here's the kicker tho, because we have
GSM (im assuming ur not on At&t TDMA), when you get new phones,
sim cards can be swapped to any phone. You could call and say you recieved a new phone that you want an exchange for, and it would take 24 - 48 hours for the exchange process to occur. The disadavantages include the $35 deductible and the fact that you can only make 2 exchanges per year. This generally covers lost or stolen phones so they don't expect your old one back. You could sell it on Ebay or something. They do take exceptions that you broke it or something.
My favorite of the two however, is the warranty exchange program. For $5 a month as well (be very specific when you call at&t to order this, warranty exchange and insurance are about the same but very different), you have the option to call lock-line and say you want to exchange your phone. If they no longer carry your phone in stock, they will replace it with the successor. Otherwise, you could say you want to upgrade, and they'll charge the difference in the value of your phone, and whichsoever phone you choose to your account (depending on your phone value, this could be could). Or, you can also find a broken or non-functioning model of the phone you want, call the warranty exchange, give them the
imei of the phone, and they will send you a replacement for that. The thing about the warranty exchange program is that they really don't care what you choose to do with the phone, their only concern is whatever phone you call in for, you need to send the defective phone that you said you had back to them. If this phone is not what they are expecting, they charge the cost of the new phone to your account.
I love At&t for this. This is why i'll miss them when cingular takes over.
