Request help for N6600 (curious problem)

[gkaraan]

hello everyone!
i am facing a problem with my nokia 6600 phone, this problem is common to many holders of this phone in my country here... and effectively there is no solution...

the phone start having errors with bluetooth not openin (system error is reported or app btui.exe is closed due to an error)... after that the gallery doesn't open anymore, the browser cannot connect to the internet, camera can't take pictures (temporary overload is reported)
other different errors are reported all the time of terminated application (screensaver.exe app closed... and others)

the most curious also is that when i turn the phone on and off many times (sometimes it takes 5-70 times) it get to work again... but when i turn it off again the same problems rehappen...

the more curious is that i have already taken my phone to the nokia service center 2 times in one month... they flash the firmware, test everything, charge u... and the phone is repaired...
but after one week of working perfectly, the phone is buggy again...
though the technicians at nokia always say that it is a software problem and that the hardware is working perfectly...

i am starting to get tired from this...
i have tried formating the phone and freeing memory and these details...
plus i have already flashed my phone 2 times (and it's not efficient and ain't a permanent solution... plus it's very expensive 30$ per flash)

maybe it's due to a particular application i install on my phone... i dunno...
but has anybody got a clue? could anyone help plz?
i would appreciate any suggestion...

Sincerly,
