Yes, I know O2 has got loads of press lately, but I recently stumbled across something worth mentioning. Recently someone posted on our forums that they'd seen a Nokia N95 on O2 bundled with an 8GB microSD card.
If you know the original N95 specs, you'll know Nokia says it supports up to 2GB, but after a few calls to O2 and Nokia, I finally found out that this particular 8GB card was developed by SanDisk and does indeed work on the original silver .
So, if you can't wait for the Nokia N95 8GB to appear on networks other than Vodafone, which I advise you to do as it's a better phone, then you can pick yourself up a Nokia N95 with 8GB of storage on O2 right now.
I'm very keen to inspect this microSD card up close, the O2 Web site says it's a microSDHC. O2 are sending me some soon and I'll keep you updated if I find out anything more interesting.
