I recently upgraded my iPhone to iOS 4 and like many others I noticed that everything slowed WAY down.  luckily I ran across an articled called Speed Up iPhone 3G + iOS4 with a Hard Reset? which gave some very good advice.  Basically the fix calls for  a double Hard Reset.

To perform a Hard Reset, press and hold the Home and Sleep/Wake buttons on your iPhone simultaneously for 5 to 10 seconds.  After a few seconds the Slide to Power Off notice will appear, ignore this and keep holding down both buttons.  In another few seconds the device should abruptly turn off, followed by the Apple logo and a reboot. Now release the buttons.

If your iPhone remains powered off, wait about 15 seconds then boot the phone by pressing theSleep/Wake button.

The tip mentions that it may be necessary to perform the Hard Reset twice to get the desired effect.  I tried this on my iPhone 3G. I performed one reset and it rebooted immediately.  Before repeating I checked to see if I could notice any difference: maybe, not much, kinda hard to say.

I then did a second Hard Reset and this time my phone stayed off.  Rebooted again, and was happy to find that yes, my iPhone does seem to be peppier – or rather, back to it’s normal pokey nature instead of incredibly sluggish.  Apps load faster, Mail messages open quicker – yay!

A bit of Googling yields little information as to what exactly gets reset during this operation.  What I found just notes that the iPhone is a computer like any other, and a hard reset typically clears all RAM buffers, caches, etc.  That can indeed help with performance.

Worth a shot.  If this helps – or doesn’t – with your iPhone, let us know in the comments.

Based on user feedback the Double Hard Reset (“DHR”) does appear to help a large number of 3G owners.

There is a certain coffee shop nearby that I frequent when I need to get some work done away from home.  The WIFI there has always been a little strange and has never really got a long with my iPhone and sometimes I cannot connect to my Netbook.  This has been going on for months.  Today I decided to take some action.  

I was pretty sure that the issue was related to outdated firmware (which it was) on an ageing router so all I really needed to is update the router’s firmware and all would be good.

Here is my journey to upgrading the WIFI in my local coffee shop.

When I purchased my iPhone I did not realize that MMS was not supported.  When my friends sent me photos using their phone they did not understand why they didn’t come through. Afterall, I do have an iPhone.

AT&T is promising MMS on September 25, along with a software update to enable it.  We’ll see!

With the release of iPhone 3.0 tethering just got easier and there is no longer a need to jailbreak your phone!    Just run a little command in terminal (Make sure you are on OS 3.0 on a 3G iPhone and iTunes 8.2):

defaults write com.apple.iTunes carrier-testing -bool TRUE

After that, the steps become a lot more simple.

1. Download this file (for AT&T) and mount the disk image (thanks Gizmodo) for other carriers, try here.
2. Option-click on “restore” in your iTunes with your iPhone attached.  Browse to the opened disk image file and hit OK.  It will update phone settings for a few seconds.
3. You have tethering.  Now go into your iPhone/settings/general/network/Internet Tethering and turn it on.

Boom – 3 steps to tethering…
