guys on a lookout for a new phone for my dad. My eyes are on iphone 4 as my dad is not such a heavy user. His main use is instant mails and calls so good battery back up is a MUST. So what do you say , will iphone 4 hold up for whole day with sync on and around 2 hours of calling, 10-15 texts, some clicks etc ??
If instant email, I prefer android over the iOS. Whether you set it up for manual update or periodical(lags the battery). Else with sparrow push from cydia will do some better. I believe it will be a little let down with whole day sync + 2 hours of calls for battery. But juice case would be better.
