I see you were hood winked. I had the misfortune to take on a contract phone that was a Samsung P200 and it was a constant pain and money drain from the dropped calls, miss billed and charges applied for roaming when my provider was "In Area" and so on. I then switched to a Sony phone and have had no problems with it and it didn't require "Software" to allow the phone to charge via the USB socket of a computer. One thing Samsung phone look for when stuffed in to a USB socket is if the machine is Windows, under Linux the P200 charged no problem but under a M$ operating system it would simply declare that USB charging was not available. Install the Samsung suit and what do you know, USB charging is suddenly available...
A lesson to the wise, aware and privacy conscious... Most products that "Require" software to perform the most basic of functions should be treated with suspicion and especially where your device holds personal stuff like contact lists, etc.
I have to say the newest sony phone I have appears to have gone down that route yet the old sony phone which is about 2 years old now works a charm and charges from any USB without the requirement of software.
sorry about flaming you before, I was kinda having a moment...
I don't have any instruct-ables as I don't believe in reinventing the wheel, most of what I would have instructable'd on has already been done, done again and over done by some other person.
When you sweep away the kiddied building Kernx / lego crap and FLUNKERS like this, as well as all the illegal stuff like dumpster diving, it is illegal as is using power from a telephone socket and other dangerous or downright stupid stunts guised as instruct-ables... you begin to see some truly ingenious inventions.
Its time waster posts like those that make this site look trashy and less appealing than when it first started.
I now prefer to use eHow sites as they are more "Educationally" geared and better structured.
I come here to keep up to date with any changes in some of the projects that are on this site that are truly worth the time to spend.
So go play with your lego or kernex or whatever the latest whiz bang toy is the sliced bread of the moment.
