After reading all the reports on the (little) changes in 1.1.4, I decided to upgrade from 1.1.3 and specifically try out the Safari "white-wash" fix. In the past, the iPhone clearing out its cache in Safari was very pronounced, as you could only open up 2 (sometimes 3) full fledged internet pages and maybe 4 or 5 iPhone optimized pages before opening another would cause the pages in the background to "white out". This is assuming you are not playing music. If you were playing music while doing this, you'd get even less pages to be able to stay loaded with content simulatenously. This has changed so dramatically in 1.1.4. They may not stay loaded with content for a long time (1 or 2 hours, haven't tried it yet), but after just upgrading my phone, I loaded up 7 different iPhone optimized pages, and 1 full fledged website. Impressed with its ability to now keep all of them populated, I went to the iPod and started playing a Coldplay song, convinced that this would cause a cache cleanse. But it didn't. I can still browse all 8 windows. Amazing. Gotta give it to Apple, instead of just giving you a phone that can do all you PAID for it to do, they constantly optimize the sh*t outta everything going on in the background, giving you more bang for your buck. God I love this phone.
