Just tried it on my 7100t... installing it wiped out the extra themes and reset my unit to default.. A little concerning, but all my data was still there.
Reinstalled the other themes (Default is the best except for the fuzzy top of the background pictures) and it's working.
But... The weather function says:
Error: could not open tunnel- failed
It also shows no appointments for today, even though there are 4.. They are all in the past? hmmmm? I'll check tomorrow to see if it only picks up future appts.
