I have one of these phones and can recommend it (for the money)
Its pretty good for a chinese phone similar quality to a zte, here is a quick summary of what I have found:
Pros:
Speed plenty fast enough with the latest dual core Mediatek chipset
Runs Video chat/skype/gtalk no problem
Screen is bright and clear if a little too bright for night use on minimum setting
Runs a clean version of Android ics
Dual sim integration is works well,as do wifi,bt,
Battery life is good enough I normally get 24+ hours if I use it as a phone although it takes a big hit using smartphone functions- on a recent trip I managed to get 2hrs 10min of HD video and then 90Mins Kindle reading before the battery went dead from a full charge- of course it comes with a 2nd battery so I could swap that straight in.
5mp Camera is fast with autofocus.
Cons:
Mic was very quiet- I had to strip the phone(4 screws) and found the moulded rubber sound channel to the mic was missing a hole (not cleared after moulding)where the to allow the sound to travel through. After poking a new hole through it the muffled mic was no more
.
Battery has no fast charge so takes about 4hrs to charge which is a pain, so I bought a universal charger to charge the 2nd battery
Photos Have a lot of noise in them I dont know if this is the jpg compression I havn't investigated further it takes reasonable snaps with good colour balance
Sensors : no compass or 3axis gyro so AR apps dont work
Support- typical Chinese mobile dont expect much -
I would expect you will need to tinker with it china-iphone.ru is fairly active though
if you need to reflash the rom if you get one with a chinese language you will need to use SP flashtools on a PC
Bundled headphones terrible went straight in the bin dont know why they bother
Oh not yet tried HDMI - I think there were some issues mentioned on the russian forum.
