We reviewed the updated handset just last week, describing it as adding 'some serious punch', but still being slightly confusing in terms of size. After all, it was originally pitched as a mini tablet. Anyway, if you bought it, you'll probably be comfortable with the size and even more pleased with news that the OS update is imminent.According to TechRadar, O2 has confirmed that the Android 2.2 update is incoming via the medium of Twitter, saying: 'Great news for our Dell Streak owners – the 2.2 Froyo update is coming this week!' When specifically? We don't know, but with only three working days left of it, the update should be imminent. Barring technical issues obviously.When it does land, you'll get all those wonderful headline 2.2 features, including a Flash-friendly browser, an improved interface, better exchange support and the option to use your phone as a Wi-Fi hot spot. All for free of course, that's the joy of an OS update - you get a 'new' phone without paying through the nose.If you haven't got one, the new update just might makes the Dell Streak a smartphone to consider, especially if you are a fan of the bigger screen.
