I recently installed Handcent SMS, and really like the features over the Messages app. However, for some reason one of my contacts keep showing up as an incorrect phone number. His number is 519 xxx xxxx, but it shows up as 549 xxx xxxx, but is still linked with the account. When I try to reply, it sends it to 549. I tried deleting his contact info completely from my phone, and checked that his number is not on any of the accounts the phone syncs with. Even with that, I tried texting him, and the number reverts back to 549 xxx xxxx. Interestingly, his number is correct in the Messages app.
