Installed the latest version yesterday - all looked OK until today, when a new icon appeared on the main screen of my bold with a 2 preceeding it. After finally working out it was related to App World I looked in 'my world' to find out that it was advising me of upgrades to 2 of my apps (Tune Wiki and Quick Pull).
Intalled quickpull no problem. tried to install tune Wiki and got a 'cannot find APN' or some such message. Only thing i could do was exit App world. Everything else worked fine. Could not clear the Icon on the home screen.
Uninstalled App world - icon dissappeared.
Reinstalled - icon appeared again.
No matter what I do - the icon remains (unless I uninstall App world).
