My Iphone has broken the power bottom

I would suggest rebooting your iphone.

Hold the power button (top right) do NOT release.

Now hold and (do not release). the home button (the center round button bottom of phone).

Hold both until screen goes blank... Wait for phone to reboot..and try again.

Turn iphone off. Power on holding power and home at same time for 10 seconds, then release power button but hold home for another 30 seconds. Screen will stay blank but should be in DFU recovery mode. Plug into iTunes and recover.

There is no other way to switch on or off the iphone apart from the power button.

The last row of icons which is the bottom row with Phone iPod etc?
It sounds as though your digitizer is bad, the iphone digitizer is delicate and seems often goes bad.
does your unlock screen work?
the bottom off the screen handles the unlock and bottom icons.
if your unlock switch works then you may just have a software problem going on.
reboot your phone by pressing and holding the power and home buttons until the apple appears.
when it reboots see if it works properly, if not you may have a bad digitizer.
is your iphone a 2G or a 3G?

First do the following : hold down the Power and Home buttons until you see the Apple logo, then release BOTH buttons, allow phone to boot, hold down the Power and Home until you see the Apple logo, then release BOTH buttons, your iPhone should now work right, if not, than do the following:

If it is a blank white screen then your lcd is broken. you would need it to be replaced. to be sure its broken. let the iphone power up and after 5minutes plug it into itunes. if it connects normally then this confirms that the iphone lcd is broken. if not try to do a restore.
