I've been running Froyo (2.2) on my Desire for several months and as part of that i get the option to 'update all' my apps at once without having to select each one individually. the problem is that after downloading a few updates I get an 'installation unsuccessful' error citing low storage space as the cause. Is there an app i can get or some way to prevent the cache (or whatever the cause is) from filling up so I can get these update to proceed?
