I have a BB870 with Dobson Cellular One. They just recently merged with AT&T and as a result have not kept up with their website information. What OS, software, etc. is the most current that I should be using?

See http://www.blackberryforums.com/gene...tml#post711408 at the top of this forum.

ATT has a site for software but if it's working i would let it be until your sure what OS is supported by the new carrier and your service.
