The earlier software/firmware really is unstabble...
But the latest firmware was improved and it was OK right now...
I've experienced this problem when I purchased my n73 with v3.06xx.xx.x firmware (not really remember the version)...
I can't zoom any image in my n73..it say memory full...
But when I updated via Nokia Software Updater, the problem gone and my n73 run a lot faster with v3.0705.1.0.31 firmware...
Of cause n73 can't run as fast as any SE phone or Nokia s40v3 phone due to Symbian OS that it have...
Even my friend's Nokia 6233 run faster than my n73...
If you want to take pics and don't wan't slow phone, why don't you choose k800i...?
It also got 3.2Mpix camera with autofocus like n73's camera...
Just my opinion...
thought about k800 also but the phone look like a brick lo... hehehe... for girls very bulky oh...
haih how la... dunno should i keep the current w850 or buy n73...
n73 really slow meh... why la... such a pretty phone...
