O2 has joined the bandwagon of service providers who sell Sony Ericsson Xperia X10 but just in black for the moment. Online business partners viz., mobiles.co.uk and dial-a-phone are providing deals from O2 for the first Android phone from Sony Ericsson.

O2 is offering the phone for £30 per month as the lowest rental including 600 minutes and unlimited texts but no free internet access. The total cost of ownership thus works out to be £720 over the two year contract period which is by all means high compared to T-Mobile’s tariffs for HTC Desire.

If you are looking for a cheap monthly tariff, Vodafone offers the X10 Black for £320 upfront payment and a £10 monthly contract for two years. The TCO works out to be £560 though you get insufficient 75 minutes and 250 texts per month.

O2 has meanwhile delayed its home phone service launch which promised to cut down the combined cost of connectivity in all forms including broadband, fixed telephony,  and mobile telephony. It is expected for May 2010 launch, now.

Online mobile phones retailer obil.co.uk expects stocks to arrive early April and is already taking in pre-orders on the Xperia X10. The pre-order however does not include O2.
