First One. I just purchased a Sony 1G and it came with a Memory Stick Duo Adaptor.What is it?
Second One. I might upgrade to 2.7 just because i have a wireless innernet router but i was wondering if x5 will work on 2.7. My current version is 2.6.(im guessing it wont work but just wondering).
The memory stick duo adapter is for device's that use Memory Stick Duo cards!
And i don't see why your x5 (i assume it is a router as i don't actually know) wouldn't work on 2.60/.70
If you want flash then yes if you want h/b then no, easy as that!!!
