Click on the icon below to download the current beta. After you have saved it to your hard drive you need to un-zip the file, this will likely be done automatically or by double clicking on it. You must be accepted as a beta tester to use this file; if we have not confirmed you as a tester, this software will not work.
The un-zipped folder contains two files: The No.2 Beta Application named "No.2.app" and a provisioning file named "No2Beta13.mobileprovision". The provisioning file is needed since you are not downloading the software from the App Store. Open iTunes and connect your iPhone or iPod Touch. First drag the provisioning file into iTunes (into the "Library" area on the left side of the iTunes window). Second drag the No.2 Application to the same place. iTunes should ask you if you want to replace the copy of No.2 that already exists (you do!).
Next you should sync your iPhone or iPod with iTunes and the No.2 beta will be installed. When you first launch No.2 there may be a longer pause than normal (several seconds) while the software scans your files to delete any corrupted preferences. This also means No.2 will start on the first documentation page. Other than fixing several bugs, No.2 will now lift the pencil when you remove you finger from it. This is the easiest way to be sure you have the new version (previously you had to tap with a 2nd finger to lift the pencil, now you can just let go of it and it will lift).
WINDOWS USERS - Windows users will see the No.2 application file as a folder named "No.2.app" You can drag this entire folder into iTunes. It is possible that inside this folder is another folder with the same or similar name. If the first folder doesn't work, try dragging only the second one that is inside into iTunes.
