DUI charges are very difficult to exphunge in GA. If you are confident the charges wil indeed be expunged and have some timetable for the process...you would benefit from waiting until they are expunged to apply.

Are your charges in Gwinnett County State Court? If you have no record you may be eligible for pre-trial diversion. Finding a phone and then trying to return it doesn't sound like much of a crime.

A person commits the offense of burglary when, without authority and with the intent to commit a felony or theft therein, he enters or remains within the dwelling house of another or any building, vehicle, railroad car, watercraft, or other such structure designed for use as the dwelling of another or enters or remains within any other building, railroad car, aircraft, or any room or any part thereof.

Can you be convicted? Yes. Is it likely you will be convicted? That is a different matter entirely. I urge you to speak to a skilled lawyer in your area as soon as possible so that you can get some peace of mind about your options.
