Finally, saw some news on Adobe Acrobat Reader for Windows Phone 7. Right now, there is no software that supports PDF format.
From Forbes’ report,
Expands PDF access to mobile devices with free Adobe Reader X for Android, Windows(R) Phone 7 and Blackberry Tablet OS. Safer viewing of PDF files with new Protected Mode security capabilities in Reader X.
The new family will be Adobe Acrobat X. Currently, the shipped date is within 30 days.
Acrobat X and its associated products are scheduled to ship within 30 days, with availability through Adobe Authorized Resellers, the Adobe Store and Adobe Direct Sales.
So, hopefully, the Acrobat Reader X can be released much earlier as it should be free for download.
