I downloaded some themes with the browser but now I have two zip files in a folder on my BB but I don't know how to unzip them, where I need to put them so it picks up the themes or how I get them where they are supposed to go.
To unzip these files download winzip from WinZip� - The Zip File Utility for Windows - Zip/Unzip, Encrypt/Decrypt
Then unzip and place all the files on your desktop, start your bb device manager and click on app loader, then click on add and point the popup window to the location you used to unzip the files, click next and you are done.
Try Aerize Explorer 2008 - File zip|unzip utility. You can download a trial and unzip your themes. If you like it, buy it. You can find the software in the Crackberry store by clicking here
