Buymobilephones is offering the Samsung Galaxy S II for £15.50 per month on a 24-month contract on T-Mobile with the offer lasting until midnight on the 5 June (that's the T-Mobile Small Internet). The phone costs £338 SIM free on Amazon which means that the contract itself sells for £34.
The contract includes 100 minutes, unlimited texts and 250MB mobile browsing which will suit a light user. The phone comes with a dual core processor clocked at 1.2GHz (an Exynos 4212), 1GB RAM, 16GB onboard storage, a 4.3in WVGA Super AMOLED Plus touchscreen, GPS, Wi-Fi, a microSD card slot, an 8-megapixel camera with a front facing one, Bluetooth, Android v2.3 Gingerbread with Touchwiz UI and upgradability to Android 4.0 Ice Cream Sandwich.
You can also get the same price of Sony Xperia U Black or the HTC One S, two technically inferior smartphones. The Galaxy S2 has been superseded by the Galaxy S3 which was launched in early May 2012 and costs as little as £26 per month.
