C905 vs C905a!

Hi all,

I'm about to get my hands on one of these but I'm not really sure which one I should go for. As far as I know, the major difference between the two is the 3G bandwidth, apart from their slightly different feature sets which I'm not really sure of (does the C905a support wifi?).

I won't be getting any data plans (hence not using 3G) and will rely on Wifi for the most part. I'm guessing most of the unlocked C905's I see on online stores (or pacific mall if you guys know what it is ) are C905 and not C905a, right?

Please help me decide, thanks in advance!!
