My cell provider recently put in some weird force configuration nastiness which forces newer devices. When I typed a really long SMS to my girlfriend, I ignored the subtle warning that it would be converted to MMS. Next thing I know, I ended up with extra charges on my phone bill. Is there an app or something that can split long SMS message into 160 character regular messages and send them separately without letting my provider know what I am doing (I do not want my phone to get blacklisted by IMEI).
