i have moved this thread to the Droid X section, where all the subject matter experts can help you along your path of getting your friend situated.
but first let me try this.
if your friend figured there were apps that were causing the freezing, and she uninstalled them, why reinstall them?
also do you have ATK(Advanced Task Killer) on the device? if so uninstall it!
a list of apps may help but probably not, when does the device actually begin to freeze up? during applications? or during other tasks? more info on that will be needed to give you the correct answer and get your friend ready to enjoy her phone again
