Looks to be a great phone for the money.
This is similar to the Huawei G510 that was posted here previously
, but this Y300 model has the smaller 4" screen so may be more comfortable for people with smaller hands. This one also comes SIM free, so won't require unlocking and won't have the Vodafone splash screens that the G510 had.
Android 4.1 Jelly Bean, MicroSDHC slot, removable battery, reasonable processor. Only 512MB of RAM but with my use of the G510 so far I haven't found this to be much of an issue.
Carphone Warehouse will sell it from £59.95 + £10 top up from tomorrow.
