		<description><![CDATA[Replacing a dead iPhone battery
http://www.edn.com/electronics-blogs/brians-brain/4441295/Replacing-a-dead-iPhone-battery-?_mc=NL_EDN_EDT_EDN_weekly_20160128&amp;cid=NL_EDN_EDT_EDN_weekly_20160128&amp;elq=ec28ae117ab744f78dcc12fd385a63a0&amp;elqCampaignId=26717&amp;elqaid=30561&amp;elqat=1&amp;elqTrackId=76601df36ad24881a0641754e1f4b01b

This was my work (Verizon carrier, versus personal AT&amp;T carrier) phone, and it was a Friday, so instead of switching to a different handset right away I ordered a replacement battery (complete with toolset) for $20 from Amazon with free Prime two-day shipping. It arrived mid-day the following Monday, and I set to work on the swap right away. Bafflingly, the battery-plus-tools didn&#039;t come with any installation instructions; fortunately, iFixit came through once again. I recommend that you supplement this writeup with a perusal of their battery-replacement guide, which also includes additional images.

Removing (and replacing) the battery is relatively straightforward, thanks to iFixit and using the included plastic tool. The most challenging bit is not losing the pressure contact mentioned in iFixit&#039;s instructions

Good news: when I got everything reassembled and turned the phone back on, it smoothly booted to full-on operation with a 75%-charged battery indication. Bad news: when I plugged it into a charger to top off the battery, it once again began rapidly discharging. I at least had sufficient new-battery power to get my stored photos off it, but it&#039;s obviously reached a point of terminal demise; I suspect that the charging circuitry itself has failed.]]></description>

		<description><![CDATA[Six months under water and iPhone 4 STILL WORKS
http://www.reghardware.com/2012/10/11/six_months_in_lake_and_iphone_still_works/

In April 2012, though, Ken Hovanes accidentally lost his Apple hardware in Smith Lake, Alabama. Unable to see far into the murky depths, and seemingly unwilling to go for a blind diving expedition, Mr. Butterfingers gave up all hope and bought a new phone.

This weekend, however, the lake&#039;s water levels were low enough to see part of the the bed, and Hovanes not only found his old phone, but managed to get it working again. Just about.

Apparently, after cleaning it up and drying it out, the phone turns on and the touchscreen still works. There&#039;s no sound and the battery is kaput, but Hovanes is still overly impressed with the iPhone&#039;s durability, sharing his story on t&#039;interweb. If only it would connect to his computer.

Of course, we only have Hovanes&#039; word for the story, though his pics do do show an iffy backlight, a bulging battery and a cack-covered casing.]]></description>

Responding to earlier reports that Apple hasn’t offered developers parts or specs for next-generation Dock Connector accessories, additional sources have confirmed to iLounge that Apple will be the exclusive initial vendor of a new Dock Connector Adapter, to be sold individually and/or in three-packs. According to sources, the Dock Connector Adapters will sell for approximately $10 each]]></description>

		<description><![CDATA[Apple iDevice dock port to drive wireless streaming
Analog audio out, AirPlay in
http://www.reghardware.com/2012/09/03/apple_dock_connector_update_to_drive_wireless_streaming/

Will Apple&#039;s new dock connector, expected to debut on the iPhone 5, signal the end of low-cost audio docks? The makers of such kit seem to think so.

With no analog lines in the new connector, there&#039;ll be no simple port converter product either.

Ditching analog out will have not only helped Apple slim down the iDevice dock connector, but it will also drive speaker manufacturers and users toward wireless streaming using Apple&#039;s own AirPlay tech, or over Bluetooth.]]></description>
