Because I am not as computer literate as most of the folks on here, when I accidentally erased all of my icons by attempting to rearrange them using the "customize" application via jailbreakme, I found this simple solution:
1. Connect your iphone to itunes.
2. Click "restore to factory settings" (don't worry, you will be able to restore the phone to it's pre-jailbreakme state, and then simply re-download jailbreakme.com and install whichever apps you want)
3. When the process is complete, you will be asked if you would like to restore to your backup iphone settings (or something along those lines)
4. Choose "yes," and you will be back to where you started before using jailbreakme.com
PROLOGUE:
5. After downloading on jailbreakme.com for the second time, I thought for a moment that the icons may still be gone, but thankfully, they remained in place...I am now putting the essentials back on:
JAILBREAKME.COM (APPsnapp is what you will be prompted to download) WORKS SO AMAZINGLY WELL, THAT I FIND THIS METHOD FASTER, AT LEAST FOR THE COMPUTER ILLITERATE.
PLEASE NOTE I AM WORKING ON WINDOWS, AND CANNOT VOUCH FOR SIMILAR RESULTS WITH A MAC
Hope this helps anyone who was just freaking out as much as I was

Don't hate on jailbreakme.com just because of this one silly "customize" application bug.
Peace,
