Howdy. I was reading your V3C to Apache thread, because I have a similar problem, only I'm going from a Nokia 6275i to a Vogue (and I'm on Aliant)
Phone service seems a little flakey, but I think that's because of a GSM dialer. SMS works very well. I can't get online though, and with unlimited data, it's reallly frustrating. Any hints or assistance would be greatly appreciated.
By the way, how does the TP2 work? I've been wanting one of those since it was introduced. The only gotchas I can see are the CDMA vs HSPA bands, which keeps me from just ordering a T-Mobile TP2 from eBay. It looks like you need 6 bands and both CDMA and GSM for a real "world phone".
