If iPhone calls your voicemail service when you tap Voicemail in Phone
If the voice instructions prompt you, enter your voicemail password. Otherwise, wait
until you hear any voice instruction, then end the call. After a time, Voicemail should
become available again.
If you can’t add or play a song, video, or other item
The song may have been encoded in a format that iPhone doesn’t support.
The following audio file formats are supported by iPhone. These include formats
for audiobooks and podcasting:
 AAC (M4A, M4B, M4P, up to 320 Kbps)
 Apple Lossless (a high-quality compressed format)
 MP3 (up to 320 Kbps)
 MP3 Variable Bit Rate (VBR)
 WAV
 AA (audible.com spoken word, formats 2, 3, and 4)
 AAX (audible.com spoken word, AudibleEnhanced format)
 AIFF
The following video file formats are supported by iPhone:
 H.264 (Baseline Profile Level 3.0)
 MPEG-4 (Simple Profile)
A song encoded using Apple Lossless format has full CD-quality sound, but takes up
only about half as much space as a song encoded using AIFF or WAV format. The same
song encoded in AAC or MP3 format takes up even less space. When you import music
from a CD using iTunes, it is converted to AAC format by default.
Using iTunes for Windows, you can convert nonprotected WMA files to AAC or MP3
format. This can be useful if you have a library of music encoded in WMA format.
iPhone does not support WMA, MPEG Layer 1, MPEG Layer 2 audio files, or audible.com
format 1.
If you have a song or video in your iTunes library that isn’t supported by iPhone, you
may be able to convert it to a format iPhone supports. See iTunes Help for more
information.
If you can’t open an attachment in an email
The file type may not be supported. iPhone supports the following email attachment
file formats:
 .c, .cpp, .diff, .doc, .docx, .h, .hpp, .htm, .html, .m, .mm, .patch, .pdf, .txt, .xls, .xlsx
