There tips came from Apple, Inc., according to an Infoworld article: http://infoworld.com/d/mobilize/app... overheating-961 " * iPhone 3G and iPhone 3GS should be used in environments where temperatures remain between 32 degrees and 95 degrees Fahrenheit. Temperatures outside of this range could decrease battery life temporarily or effect performance. * iPhone 3G and iPhone 3GS should be stored in locations where temperatures remain between -4 degrees and 113 degrees Fahrenheit. Note: Temperatures within sealed motor vehicles can exceed 113 degrees Fahrenheit. iPhone owners who don't follow these suggested best-practices could experience any of the following "symptoms:" * iPhone could randomly cease charging * * iPhone display could become less bright * * iPhone cellular connection could weaken or diminish * * iPhone temperature warning screen could appear, rendering your device useless except for making emergency phone calls Apple also included the following suggestions, though most of these are simply common sense, at least for experienced gadget users: * Don't leave your iPhone in a vehicle during a hot day * * Don't leave your iPhone in direct sunlight for any extended period of time-Avoid using data intensive applications, like GPS or streaming- media apps, for extended periods of time on hot days or while in direct sunlight. Note: Apple's iPhone overheating tips appear to be aimed specifically at iPhone 3G and iPhone 3GS owners, but I'd say they're equally applicable to first-gen iPhone users. I'm guessing there's no temperature warning screen on the original iPhone, though.)" This may be the reason why the iPhone doesn't have the most popular streaming codecs...like Flash, Windows Media, Real Media, you know, the ones the webpages actually USE, not the ones Apple wishes they used. So, to prevent your iPhone from overheating, avoid using data intensive applications like GPS (street mappers?) or streaming media (what streaming media?) for extended periods (over 2 minutes? 5? 10?? What???) on hot days (all days are hot days! IT'S SUMMER STUPIDS!) or while in direct sunlight (only operate your iphone INDOORS with AIR CONDITIONING set to COLD or in a walk in cooler if you can.) ============================================================== OK, they're trying to blame the battery for the overheating. Huh?? How can the BATTERY be overheating? It's not CHARGING during this time when batteries get hot. The new iPhone is just SO efficient, drawing so little current and with such a long runtime, the DISCHARGE rate is so low how can the battery get warm at all?! http://americanpatrol.com/POPUPS/IM... What overheats in a RUNNING computer?.....THE OVERCLOCKED PROCESSOR! New Iphone runs 600 Mhz in a tiny thin box with NO COOLING WHATSOEVER! Is it any wonder that if you load up the CPU with processor-intensive apps like GAMING or GPS/Mapping or STREAMING it's gonna OVERHEAT?!! Duhh.. http://www.tetraultdesign.com/samso... HAVE NO FEAR! The iPhone Freon Cooler is being designed as we type! Watch for them all in every consumer electronic store/site in 3 months. Everyone will want one...It'll be SOOOO COOL! There ARE solutions: http://www.colorado.edu/ASEN/asen55... Text.htm Look at "mega flats" on this page.... http://www.norenproducts.com/Heat_P... They'll figure out some kind of passive heat pipe solution so as not to eat the battery further than it is now: http://www.crazypc.com/products/hr-... archived from misc.phone.mobile.iphone

That is another very useful feature few electronic devices have, even many high-priced PC CPUs are difficult to temperature manage. I am impressed. I street skate with my iPhone 3G in 104° real world weather. Will see. archived from misc.phone.mobile.iphone
