X32 or X64 ?
 

Hello. My brother is going to replace my unlocking computers. He wants to know if it's better to install X32 or X64. There isn't any problem with X64 ? Thank you for your fast reply.

on X64 you might have some problems with phones drivers installations. Some samsung drivers are not available in X64 version.

xp sp3 32bit

this is my meaning ...

for Unlocking and flashing system, 32-Bit is best ...........

And what about Windows 7 ? What is the best, windows XP or Windows 7 ? And what is the best configuration for unlocking and flashing job (RAM, OS, hard drive, etc) ? Can you advise me please ? I will have 3 new PC and i have about 10 unlocking boxes.
Thank you very much.

2 gigs of DDR-2 RAM on Dual Core or Core2Due Intel on Windows XP2 32bit is enough.

Laptop is not bad at all,
and make sure you have UPC Storage ( Electricity ) for safe work.

windows 7 is not bad also, but not really compatibile or stable with Smartcards and Boxes drivers.
