[DEATH-INCARNATE]

hey guys

iv been having trouble with my Nokia 7610. when i try running a application that iv downloaded from the internet my whole phone lags up or freezes, but i could run apps fine a few days ago. I cant remove any progs(ie its says it removin da prog but neva removes da prog no matter how long u wait for it too). also i can install any new apps from da net. iv tried reseting to da factory settings n it doesnt help, it wont let me format my mem card. iv goin to da nokia shop to have them delete da firmware n re-install it again, but coz my phone is out of warenty they want a fortune to do it(ie: R150, thats about D$23). plz help me. im lost without my phone

thanks
