Here's a little something for iPhone owners, at least if you're looking to enhance your phone's text messaging capabilities. Developer Shawn.Chain has recently released weisms, a homebrew that functions as a native SMS application for your choice Apple phone. Here are weisms' current features - the last three were recently added as Christmas specials:

• Search your message
• Forwarding received message
• Delete message one by one
• Send message to multi-recipients
• Send contact information via SMS
• Support smilies in Message
• User could create pre-defined texts and append them into message
• i18n support
• Display unread messages in springboard
• Suspend to background instead of quit if Home button is pressed
• Support long sms perfectly
  

Weisms v1.0 currently carries two language settings - English and Simplified Chinese. Installation instructions should be available over at Shawn.Chain's site. You may also want to contact the author in case you encounter any bugs.
