Just got this thing a few days ago. Added like 8 e-mail accounts. the first couple days i was getting all my e-mails very quickly. now, i haven't been getting them or there is a serious delay in getting them. i tested and e-mail about 10 minutes now and still haven't recieved. Is this normal for it to sometimes have a lag? What would account for this? And, is there anything I can do to fix this? i do usually have at least 3 bars of 3G signal. Thanks in advance.
