I'm a bit confused as to what's going on with iStat on my iPhone 4. Now, we know that the 4 is confirmed to have 512mb of RAM. I just rebooted my phone, and iStat is confirming this with the following read: Wired: 62mb Active: 45mb Inactive: 23mb Free: 295mb Total: 423mb. However, after having used my phone for a few hours, I noticed that the wired/active/inactive/free totals only add up to about 200-300mb. Anyone know why iStat would be varying it's numbers so wildly?
