The T-Mobile Rapport (also known as the Huawei U8180 or Ideos X1) can now be had from Asda for as little as £49, without the need to top up.
The handset comes with a SIM (included), six months free internet worth £20 as well as £20 worth of Android applications as part of its Appy Christmas campaign.
The rest of its features make it a decent entry level Android smartphone. There's a 2.8-inch 320x240 pixel capacitive touchscreen (same as the HTC Wildfire), a microSD card slot, 256MB RAM, 512MB ROM, Wi-Fi, Bluetooth, a microUSB port, a 3.2-megpaixel camera, Android 2.2 Froyo and a Qualcomm MSM7225 chipset clocked at 528MHz.
Its 1200mAh battery should last for up to four hours in talktime and it appears to be easily unlocked as well.
The same handset costs a whopping £65 at Amazon and £70 at Argos. Both Vodafone and Orange sell the phone, as the SMART and the Stockholm respectively, but none for as cheap as T-Mobile.
Note that T-Mobile's internet allowance is capped at 500MB but unlimited for both internet browsing and accessing emails. You can find more about the £20 apps offer - which runs until the 24th of December - here.
