Well if you want to run ISO's you should get the 1.5 0r the 1.52(requires upgrade to 2.00 and downgrade to 1.5). If you want the psp solely for UMD's get the 2.50.

Thanks for the replies.

I'll definitely want to play iso games. SO am i right to say i should just get 1.52 and downgrade it to 1.5 cuz the latter cost ard $25 more.

Another thing is if i downgrade to 1.5, can i upgrade it back to 2.5 so that i can surf web? just worried that i might change my mind along the way.

no u will eed to upgrade to 2.00 then downgrade to 1.50 the web is on 2.00 any ways so u could just keep upgrading then downdrading

yeh its pretty much on whut u want if u want the internet more go with 2.5 and if ur like homebrew go with 1.5

no dont upgrade and downgrade too much. It will break ur psp!

1.50 (small hint look by the bar code on the right there will be another sticker there is a letter under 220-240 if its an A its 1.50) and they are all the same price. i have the giga pack it come's with every thing except games but it has 1 gig memory stick(like a memory card for the ps1 and ps2 but its tiny) you can run iso's on 1.50 which is a psp game.which is good but you will be restricted to older games but not 2 worry the latest games suck

someone was saying that 2.5 can also play homebrew provided its played thru gta..is that true?

anyway from all the feedback i gathered, i guess i should buy 1.52. however, is it difficult to upgrade to 2 den downgrade to 1.5? i'm totally clueless. and lastly if i manage to downgrade to 1.5, do i still have to do something b4 i can play the iso games?
