With the recent short battery life issues occuring since the OTA, my phone is lucky to make it a day with minimal use. I am taking a trip in about two weeks to vegas and plan on using my phone heavily there for pictures and what not, so I wanted to pick up a spare battery to take with me. VZW online store is sold out of the standard D1 batteries currently but has D2 in stock and it shows the same stock part number. However the D2, according to the description uses 1420maH where as the D1 uses 1400maH. This is greek to me. I remember reading a post recently where the extended battery for the D2 was working well with the D1 and I was just curious if anyone knows if the same will apply for the standard battery. Any help from you guys is always appreciated!! Thanks!
