Does anybody know why sometimes my text will auto delete? i already checked my options and they are set to delete 30days after opened but they all delete every couple of days and this started happening. You know why dis happening?
This is a very common problem due to the low onboard memory of RIM products.
The first thing you want to do is pop the battery and do a power cycle. Popping the batter is the only way it will do a full power cycle, and it is recommended you do this a couple times/week. There is also an application called 'quickpull' that will simulate the battery break, in the event you are using ottercases or other similar products.
You will also want to add an micro sd card of some sorts, and MAKE sure to save your pictures/video and music on the card, and not on the storage of the device.
With these two steps you can usually prevent any loss of email/text.
