From time to time, O2 have flash sales which typically last for one weekend only. This weekend it’s the Samsung Galaxy S 2′s turn to be in the spotlight. The handset is normally only free on their £37 a month contracts however, with the flash sale you could technically get the handset for free on a £21 a a month contract. The contract requires you to take out a data bolt on, which you have to pay for the first month. The lowest data bolt on is £3 for 100MB, with the advertised bolt on being the 500MB bolt on, costing £6.

The tariff on it’s own however, is only £21 a month and gives you 300 minutes and unlimited texts. The contract length for this offer is 24 months, making the minimum contract total £507 if the bolt on is removed, which is only marginally more than the sim free price of the handset. The deal applies to both the white Galaxy S2 and the black model.

Buy from O2

UK carrier O2 have apparently confirmed the much circulated rumour that the Dell Streak handset will recieve the anticipated Android 2.1 update tomorrow on the network.

O2 previously announced that release of the update would be early September and Engadget have confirmed with O2 who have now said that the update is to be rolled out on the 1st or 2nd of September which is obviously great news for Dell Streak owners.

There is still no news on a date for the release of Froyo (2.2 version of Google Android OS) but, at lease Eclair (2.1) is on it’s way at last, for UK owners at least.
