I ordered this battery, because my old after 1 1/2 years faithful service slowly gave up the ghost. I was looking for a low-cost battery and thus hit on this. iPhone screwed, old battery out - new battery pure. Did this already a little in it and it seems to run very well so far! For this price: SUPER! Would buy this battery again and thus highly recommend it further!
PS: the description says that you should pay attention to the APN number. I have a different APN, but the installation went very well and the battery life has, in contrast to my old battery more than doubled !!
