Text message sig character limit?

[Dr Fatsides]

I just went to add an oh-so-hilarious text message signature to my Droid X and I could only enter "sent from my droid X so d".

is that all the characters we get???

The Blackberry user I was gonna steal the sig from had, like, all the words to Stairway to Heaven in his!

(kidding about Stairway to Heaven, but not about the character limit)

...or am I missing something - again?

TIA
