Looks like sprint will finally upgrade me to a 600 after plowing through 5 300's. Wont know for sure until mon/tues, but it the event I do get a 600, are there any issues about syncing the 600 off of the 300's latest hot sync? The only SW I'm concerned about it t-buttons - everything else is general palm sw and not treo 300 specific. If there are *any* potential issues, I just as soon remove whatever I need to from the 300, hot sync it, then sync the 600. Any suggestions?
