Tonight I got the P800 into the iSynch panel. Turns out the first iSynch try aborted and the second one is just going on and on. Cancelling didn't particularly help. I bet I get a synch by tomorrow, though.
I'm also web browsing just fine and I have my email working. There was documentation on the T-mobile site that their 24/7 tech support walked me thru. These tech people are great! It's pretty easy to get through to them (waiting no more than 5 minutes) and they are all really polite and helpful and I've tried several by now. The level 3 techs work from 8 to midnight eastern. Not bad.
Still praying for a little attachable or wireless thumboard. I enjoy the handwriting when it works, but it's still a hassle compared to thumboarding. Sent a suggestion to Sony Ericsson about it.
Everything new that I add makes me more and more happy with this device. I showed my brother the chess program. He wants one. You can play chess via SMS and can find people who want to play and be found via wireless (if you turn on the option). Cool!
