The invention claimed is: 1. A crystalline form of a compound of formula (I) wherein the crystalline form is a hydrate or is anhydrous. 2. The crystalline form of claim 1 , having an X-ray powder diffraction pattern comprising one, two, three or four peaks selected from peaks at 17.6°, 18.4°, 22.5° and 24.2° 2θ±0.2°. 3. The crystalline form of claim 1 , wherein the crystalline form is a hydrate. 4. The crystalline form of claim 3 , having an X-ray powder diffraction pattern comprising one, two, three, four, five, six or seven peaks selected from peaks at (±0.2) 9.6, 13.3, 13.9, 17.0, 18.9, 20.3, and 23.1 2 θ±0.2°. 5. The crystalline form of claim 1 , wherein the crystalline form is anhydrous. 6. The crystalline form of claim 5 , having an X-ray powder diffraction pattern comprising one, two, three, four, five, six or seven peaks selected from peaks at (±0.2°) 5.6, 7.9, 11.2, 12.3, 15.6, 17.6, 18.4, 21.4, and 24.2 ° 2θ(± 0 . 2 °). 7. A pharmaceutical composition comprising the crystalline form of claim 1 in admixture with one or more pharmaceutically acceptable diluents or carriers. 8. The pharmaceutical composition of claim 7 , further comprising a stabilizing agent selected from the group consisting of metal salts of stearic acid and metal salts of stearyl fumarate. 9. The pharmaceutical composition of claim 8 , wherein the stabilizing agent is magnesium stearate. 10. The pharmaceutical composition of claim 7 , wherein the pharmaceutically acceptable diluent or carrier comprises lactose. 11. The pharmaceutical composition of claim 7 , wherein the crystalline form is micronized. 12. An inhalation device comprising one or more doses of the pharmaceutical composition of claim 7 . 13. A method of inhibiting phosphoinositide-3 kinase activity in a subject comprising administering to the subject an effective amount of the crystalline form of claim 1 or the pharmaceutical composition of claim 7 . 14. A process for the preparation of the crystalline form of claim 3 comprising the step of crystallizing a compound of formula (I) from dichloromethane optionally in mixture with methanol. 15. A process for the preparation of the crystalline form of claim 5 comprising the step of crystallizing a compound of formula (I) from anhydrous 1-propanol. 16. The process of claim 15 , wherein the crystallization step comprises cooling from an elevated temperature. 17. A crystalline form of a compound of formula (I) having the X-ray powder diffraction pattern as shown in FIG. 1 . 18. A crystalline form of a compound of formula (I) having the X-ray powder diffraction pattern as shown in FIG. 2 .
