Two weaks ago I bought a PS Vita - I didn't know anything about hacking, I only knew it could play PSP games. However my FW is 3.57, so no TN-V. So this weak I bought another one PS Vita with 3.55 FW, cause I knew it's able to run TN-V on this version. So I registered new PSN account (US region). Problem is I don't have US credit card, cannot add my Paypal account (don't know why), so the only option is to buy a PSN Store coupon. So my question is - can I buy intead of Minima Metal Gear Solid Portable Ops + (which I could buy on my account, not the new one) and flash TN-V through this game. I know MGS PO+ has exploit and through it could be flashed 3.57 OFW. Could I flash 3.55 as well? Or there there is save with TN-V only for Minima and is not "compatible" with other games? I don't want to buy some game which I will never play for nothing. Another question is - can I transfer Minima or MGS PO+ to Vita without PS3 (for e.g.: from PC? So it is possible to download it to PC and then tranfer to Vita?). I have PC, Xperia Play, PS Vita, my girlfriend has X360, but I never had any Sony's big console (and my friends too). PS Store on 3.55 Vita don't let me sign-in even with Vita Update Blocker (in PS Vita is account of former owner and if I want to format the console, I have to update to 3.57...) so I need to transfer game into Vita some other way.
