yes, she does has the SD in the phone and most of the apps she move it to the SD.
it hangs for many reasons:
1. continue flip on FB photo album
2. software auto-updating without notice
3. games
4. even you try to be funny and flip on the photo album fast just for fun also will hang
I was like wtf..my iphone never hang till need respring it.
Hmm I'm assuming she's on G version? As some have suggested, try moving apps back to internal phone memory.
My S2 doesn't hang either. Flies through tasks with thunderbolt tweaks in fact

Do i need to "wipe" the phone if install checkrom? After wiping means my internal memory will be formatted right? And I'll have to use the backup that I've made through titanium backup in the sd card to install back the apps and my phone contacts, am I correct? Thanks.
Yeah, it's recommended to wipe. Just follow instructions in the thread on xda or wherever, they'll tell you what to wipe.
Actually, it won't wipe your "internal usb" partition, but you could make a backup just to be safe. Or manually wiping if you don't have large amounts of data which you're lazy to backup and move back in
