The default memo application allows only 100 characters. A better alternative is to use text drafts. Create a new text message and type in what you want on the memo, and then save it as a draft. This allows you to have more than 100 characters because each message can hold 160, plus you can text past 160 and it will just add another page (which really makes no difference). Another cool feature is that you can add a subject to your message, making it a picture message. When you view the text in your drafts, you'll see it as the subject (ex. my homework list has a subject labeled "homework.")
Just an idea.
LOl i always do this or used to do this as well...
But one problem
If you do too many and it gets really full it will starte deleting draft messages from oldest to newest..
it did that too me so be carefull you dont losse any personal important information...
just a heads up...
