Be sure to read the FAQ section entitled "Buying a used BB on eBay". Even if you are not getting it there, the information is still the same. You can really get burned and/or have lots of problems if you do not know what you are doing.
The 8830 works on CDMA in US. CDMA is used by both Verizon and Sprint. ATT and T-Mo technology is GSM. The two are not compatible. The 8830's GSM feature is for use outside the US as it utilizes different frequencies that are uses in other parts of the world. That being said, there are still several countries where it will not work - especially Japan. Probably more than you wanted to know however.
