Hi A.,
Beleive it or not my ten year old still loves american girl dolls to collect, (not really play with them) and calico critters, (another collection) she remains fascinated with small toys that are posable and put in a display type setting.
She loves i-tunes to downloan on her i-pod. She really does like crafts, etc., with wanting to sew and do needle point or knitting. It's a great age to encourage something like that which can become a life-long hobby.
If she's ever wanted to enroll in something, like say for example, horse-back riding or ice-skating, you could buy so many lessons and package the brochure up with a few supplies needed to do the activity and that makes it more fun to unwrap something and then she has the lessons to look forward to.
My daughter likes purses, lip gloss or very light lip-stick, girl perfume, hair accesories, art supplies, cool designer accessories for her bedroom; (matching lamp, rug, curtain valance, bed-spread (comforter) door-way beads, wall paper border etc. etc.) Those things make a great gift and you can help her "re-do" her bedroom with her! They love an accessorized room, with the lastest, coolest teenage type deco stuff.
Other than that, you just need to get creative and really drill her about what she likes to do, or has always wanted to do, (within reason!).
btw, My daughter does already have a cell-phone for limited uses only. She is not allowed to bring it to school, or anywhere without our approval. It's mostly so she can call us from a neighbor or friends house if she feels the need, or is at the movies or other event with a friend and their parents, and should ever feel the need to call me. I monitor who she is speaking with etc. etc. It sits in a drawer most of the time, but it's there so she can always get a hold of us, when she's with friends or in others social settings. (ex; She goes swimming with another family, or something.) It's all managed very closely.
Best of luck,
D.
