I,m not 100% sure how OTA works but I tried emailing some apps and themes in .jad file format that i downloaded to my laptop then i emailed them to my blackberry email thinking i could download the .jad as an attachment since I lost my usb cord. It wont open the attachment in bb email. How can I load a .jad from bb email if its even possible? I have a curve 8330 by the way
