After doing the (otherwise great) iOS4 update, I had a strange issue: whenever I viewed an email on my iPod that contained a PDF attachment, I could only see the first page of the PDF. I couldn’t tap the PDF to open it and read it. Only the first page would appear inline with the rest of the email.
After Googling around, I found that it is actually a bug that occurs when you have the apps Stanza or Air Sharing Pro installed.
Well, it turns out that I did have Stanza installed so that I could read Thoreau’s Walden, so that explained it.
Whether it’s Apple’s big or the app makers’, I do not know, but here is what I did to fix it:
* I synced my iPod Touch to iTunes to make sure things were backed up
* In iTunes, I deleted Stanza (I hear that simply unchecking it does not do the trick, but I didn’t test that to confirm)
* I synced the iPod Touch again to remove Stanza
* I held down the power button at the top and the home button until the Apple logo appeared to make it reboot itself
Once I did that, I could once again view PDFs that were attached to emails in the iOS Mail app. Would the problem re-appear if I re-installed Stanza? I’m not sure. The only reason I had it installed was to read eBooks, which Apple’s iBooks app also does so I switched to that.
Problem solved. Hope this helps someone else.
