Police routinely go through the cell phones and computers of folks busted with drugs these days. Certainly don't return the call and if police actually come to talk with you tell them very clearly (and stick to your damn guns on this one) that you will not talk with them without an attorney present, period. If you don't have an attorney with his nose up your ass following you around all the time and they press the issue, tell 'em you'll get back to them once you get your attorney lined up. That's it. They won't be able to get a search warrant off a request for a dime, and BS like a dime means $10 will just make you an obvious liar, just remain silent as silence is golden ... let your attorney make any excuses, if needed, after reviewing all the evidence against you.
