.sisx applications r SIGNED sysmbian applications but can be converted to .sisx (I mean can be signed). Though never tried one myself cos I dont use sv3 phone. Search with google, i'm sure it'll help. I'll also post the web  add asap.

Thanx for ur responses . So sorry, I wouldn't know the firm ware version b4 it happened but I know its PSP 1003k. I tink the problem started when a friend removed the cable when still downloading something on it from a system. Its almost new!

i tried to on my PSP 2 weeks ago but it wouldn't boot at all (the screen remains blank), the green power light comes up but goes back after few seconds. I'll be grateful if onedody can help me out. 10q in advance.

there r disadvantages of holding ur poop (that's if its still below threshold). Constipation is one among others cos absorption of water takes place where poop is stored.
It also depend on the type of d poop esp the one that can make u do it anywhere
