Wait you said it deleted messages by itself??? I don't know if my mom's does that. I though it deletes just some automatically I thought their was a mode that does that for her...But like I said I don't use her blackberry on everyday basis like she does since it's for her...
The only time I play with it is when she needs me to customize her phone with ringtones and wallpapers and stuff. She has a blackberry curve, but I don't remember the number..It does have that blackberry bold or tour OS though.
It does that when you have 0 memory left on the ram.
But the main cause of the problem on blackberry memory leak is apps running on the background also themes on blackberries since plazmic(theme creator for blackberry) was so buggy.
I love blackberry to death especially there are alot of apps that i truely miss(viigo, Pointe, yahoo go!, fantasy sports) its that the problem i have with rim is that they wont support their older phone after a year, and have a minor update on their newer phone(better keyboard, and a trackpad with no processor and ram update)and see that the Tour 1 and storm 1 had no update for how long while the storm 2 and tour 2 still seeing updates is straight bulls**t especially when they have the same exact spec as their older version. Its like basically forces me to update to the same exact phone with extremely minor update just because it gets support. Yeah that was the main reason why i end up jumping to droid. I still will probably get the next Blackberry device when they finally stop using the same arm 11 processor and finally get modern with it, or else it basically will be the same damn phone with a different form factor and a new OS but the same exact spec as their older phones. That is the reason why i currently still have my curve 8330 in my disapposal just incase my droid gets f**ked up out of noware. RIM should have every phone since the Storm 1, bold 1 release to OS 6 since they all have the same specs outside of wifi.
