Apply by all means but I would strongly suggest that you use the time between now and then in learning how to write (and probably speak) correct English - not textspeak.
You're young and will eventually learn that us nasty grown ups (particularly those at RAF Recruiting offices, OASC and IOT) are rather partial to those who can use their own language correctly. Might be good enough for the playground/pub in Crawley but not for the Sergeants' or Officers' Messes.
