So I see many many threads about people complaining about not being able to store many apps or anything without it running out of memory. I heard that it only has about 200mb of on board storage but it comes with a 4gb sd card that can be upgradeable to 32gb. So if that is the case, What is the problem? Can't you just buy a bigger sd card and use that to store everything? I was considering buying this phone, So i'm just wondering, please fill me in. Thank you!
