I'm in portland OR with very strong Tmobile 3G almost everywhere, my n900 looses 3.5 to 3G and it also looses the conection when switching from 3G to 2.5. in only displays a "no cellular data" available and it takes some time to find the cellular data again.
anyone experiencing the same issues? it's getting frustrating to drop the call when the phone is doing that. Shouldn't the phone switch automatically between frequencies like any other phone?
thanks
