3g vita in the UK?

I recommend giffgaff, got an email from them today telling me my old sim was about to expire since I hadn't used my N95 in over 6 months, so I wondered if it would fit in the vita (wasn't sure if it was microsim) but vita takes the standard.

They have great prices and even cheaper for data only and pay as go. I just bought a

• £5 goodybag for 500mb for the month
• £7.50 for 1GB
• £12.50 for 3GB

cheap enough to keep it as a nice perk for the month I think. Giffgaff runs on O2s network so you don't have to worry too much about coverage.
