Add to this if you can - these are the few I've found (and post up what *#0000# displays on your phone so we can be sure of software versions)

V 3.0505.2
19-02-05
RM-51

* Dust under the screen (hardware bug though)
* Beep before a ringtone or smstone is played
* Profile selection using the power button (one press) usually won't work - example changing back to general from silent
* Vibrate doesn't always vibrate when silent mode is on (esp when a SMS message is delivered to the phone)

I'm sure there are many more - they're the ones that irritate me!

Damn..I just bought mine yesterday... I haven't check it cause am so busy at this time...hhmmmm..probably now. Thanks for the info.

I have problem with PTT. Preinstalled PTT funktion is not able to add new PTT group. I fill out all four (three without thumbnail) items and press "Done" and nothing happens. With Nokia 6600 is no problem (in N6600 case is PTT extra applicaton). And I can´t receive group invitations (special SMSs´), it writes: "unable to open group invitation". Talking via PTT "one to one" is ok. So that is no problem of setting or provider (GSM). It seem to be in software. Is possible to load PTT Symbian application like in cese of N6600? Can anybody help me or confirm this problem?

Thanks CEBE
