Turn Old Mobile Videos into iPhone Ringtones

Have 3G2 video files from older CDMA phones with audio you want as a ringtone? 3G2 is a mobile video format from the 3GPP2 era that stores both video and audio. Extracting that audio and converting to M4R lets you use it as an iPhone ringtone.

Our converter handles the entire process: extract the audio track from your 3G2 file, convert it to AAC, and package it as an M4R ringtone ready for iPhone.

How to Convert 3G2 to M4R

Upload your 3G2 file - Video files from CDMA phones or legacy mobile devices
Select M4R output - Creates iPhone-compatible ringtone format
Download your ringtone - Ready to sync to iPhone via iTunes or Finder

The audio track extracts automatically. Remember: iPhone ringtones must be 40 seconds or less.

Understanding the Formats

3G2 (3GPP2) - Mobile video container developed for CDMA2000 networks. Uses H.263/H.264 video with AMR or AAC audio
M4R - Apple's ringtone format. AAC audio in MPEG-4 container with .m4r extension
Audio extraction - The converter strips the video and keeps only the audio track
Duration limit - iPhone requires ringtones under 40 seconds

When This Conversion Helps

Legacy Phone Recordings

Old CDMA phones recorded video in 3G2 format. If you have memorable audio from those recordings, convert to M4R to use as your iPhone ringtone.

Custom Notification Sounds

Short 3G2 clips with distinctive sounds make unique text tones. Keep clips under 30 seconds for text alerts.

Pro Tip

3G2 audio is often recorded at low bitrates for mobile networks. Listen to the extracted audio before syncing to iPhone. If quality is poor, the original recording may be the limitation, not the conversion.

Common Mistake

Forgetting the 40-second iPhone limit. Long 3G2 videos will convert but the ringtone will not sync if over 40 seconds. Check duration before uploading or trim afterward.

Best For

Extracting audio from legacy CDMA phone recordings to create nostalgic or unique iPhone ringtones from old mobile video content.

Not Recommended

Not ideal for high-fidelity ringtones. 3G2 audio is typically low bitrate for mobile transmission. For better quality, start with higher-quality audio sources like MP3 or M4A.

Frequently Asked Questions

Yes. The converter extracts the audio track from your 3G2 video and converts it to M4R format, which iPhone uses for ringtones. The video portion is discarded.

iPhone ringtones must be 40 seconds or less. Text tones should be 30 seconds maximum. If your 3G2 audio is longer, trim it before or after conversion.

3G2 files typically contain AMR (Adaptive Multi-Rate) or AAC audio. Both codecs convert to M4R format. AAC sources produce slightly better ringtone quality.

Connect your iPhone to your computer. Drag the M4R file onto your iPhone in Finder (Mac) or iTunes (Windows). Find it in Settings > Sounds > Ringtone.

3G2 was designed for CDMA networks (Verizon, Sprint), while 3GP was for GSM networks (AT&T, T-Mobile). If your old phone was on a CDMA carrier, your videos are likely 3G2 format.

Video quality does not affect audio quality. The audio track in 3G2 files is separate from video. However, 3G2 audio is often low bitrate (12-24 kbps AMR), so ringtone quality reflects the original recording.
